The flat plate trolley comprises a flat plate, a front support and two sets of rear supports, and a front wheel shaft and a rear wheel shaft are arranged at the bottoms of the front end and the rear end of the flat plate correspondingly; the top of the front bracket is rotationally mounted at the bottom of the flat plate; the front wheel shaft is mounted on the front bracket; the two groups of rear brackets are symmetrically arranged at two axial ends of the rear axle; the rear support comprises a supporting beam I and a supporting beam II, one end of the supporting beam I and one end of the supporting beam II are rotationally connected with the rear axle, the other ends of the supporting beam I and the supporting beam II are rotationally connected with sliding blocks, and the two corresponding sliding blocks on the supporting beam I and the supporting beam II slide in the long axis direction of the flat plate and are locked and fixed through positioning pieces. The supporting height of the rear support to the flat plate is adjusted by adjusting the opening angle between the supporting beam I and the supporting beam II. The method is particularly suitable for deslagging and blast hole drilling construction of an inclined hole engineering section, and the defects that in the prior art, the number of procedures is large, and consumed time is long are overcome.
本发明公开了一种平板台车及出渣系统,包括平板、前支架和两组后支架,平板在前后两端的底部分别设有前轮轴和后轮轴;前支架的顶部转动安装在平板的底部,前轮轴安装在前支架上;两组后支架对称设置在后轮轴的轴向两端;后支架包括支撑梁I和支撑梁II,支撑梁I和支撑梁II均是一端与后轮轴转动连接,另一端转动连接有滑块,支撑梁I和支撑梁II上对应的两个滑块沿平板的长轴方向滑动、通过定位件锁紧固定;通过调整支撑梁I和支撑梁II之间的张开角度调整后支架对平板的支撑高度。本发明尤其适用于斜洞工程段的出渣、爆破孔钻孔施工,利于克服现有技术存在的工序较多、耗时较长等不足。
